Mantis,
The discrepancy you are experiencing between what you know about yourself and what your chart says about you will not be solved by comparing different systems of astrology. (If you are going to use sidereal, then just switch to Vedic interpretation. Tropical zodiac interpretation of a sidereal chart is not valid). The problem is simply a matter of finding the correct Asc degree in the tropical system. Some of my clients have had certified birth times that were hours off according to multiple witnesses in agreement. Don't take the time on the certificate literally. You can't be both certain that you are Virgo rising because that's what the time of record suggests, yet be sure that the description of the sign doesn't fit you. YOU know yourself and if the description of the sign doesn't quite fit, that's because it isn't the correct one!
My program is running a bit hot and giving me trouble, but I'll run your data later - Thank You for posting your chart with birth data intact - and get back with you on the results. You describe a fixed sign on the Asc - its probably either Leo or Scorpio. There are ways for you to verify it for yourself using simple notations on your calender for transits (Sun, Mars, etc) across the degrees in question.
Well I have witnesses who said I was definitely born by 6:30 pm, and my official time of birth is 6:20..so not far off.
And my mother told me there was a nurse there who wrote the time down almost immediately, so definitely not "hours off".
I think I do have some typical Virgo Rising traits, like looking like a bit of an old maid(I usually wear glasses), fussy, worrying excessively, liking order and neatness, admiring, at least, if not doing fine handy work and stuff.
Especially that my Rising is in the Cap Decanate-I often got told I look nerdy and serious, and even now I do.
And I am also very brainy and actually have never had a boyfriend, or kissed anyone by this age(22), which also resonates a lot with typical Virgo "eww" philosophy with regards to sex and relationships.
Also, despite the fact that I normally don't agree with using astrology to explain medical problems, I have had a major depressive episode that lasted a few years, during which I basically stopped living, and even had thoughts of suicide, which, again, seems to resonate with Capricorn Decan of Virgo(excessive negativity), although I could think of other aspects that might explain it, as well..like a tight Saturn-Neptune conjunction(in the 4th house, whatsmore, if I use Placidus), or having a very stressed Mercury, making heavy squares to 3 planets, and also being debilitated by sign.
I would believe it possible that my birth hour might be 5 minutes off, though, which might put my Moon in the last degree of Taurus, instead of 1st degree Gemini..
However, aside all this, I think that my physical appearance can be explained by aspects, as well. Aspects from planets to the AC tend to give you traits of the signs they rule...so having Sun and Venus making pretty tight oppositions to my AC could explain the somewhat "fixed" traits, like wide face, squarish jaws.
A few Pisces with Virgo AC opposite their Suns include Kurt Cobain, Bruce Willis, and Sharon Stone..I think they could all pass for Leo Risings.
